Implementation of a telemedicine geriatric co-evaluation in the emergency department: a prospective pilot study.

  INTRODUCTION: Complex drug management is a common challenge in the treatment of geriatric patients. Pandemic scenarios, such as the current one (COVID-19), call for a reduction of face-to-face meetings, especially for elderly patients. Therefore, the aim of the present study was to compare the innovative concept of applying telemedical assessment to geriatric patients in the emergency department (ED) with ED standard treatment. The therapeutic recommendations regarding drug management from the two assessments were compared. A special focus was the use of potentially inadequate drugs (PIMs) for geriatric patients according to the “Fit for the Aged” (FORTA) classification. METHODS: 50 patients (40% female) aged ≥70 years and assessed with an Identification of Seniors at Risk Score (ISAR score) of ≥2 admitted to the ED were prospectively enrolled in this study between November 2017 and February 2018. In addition to the standard treatment in the ED, co-evaluation via video transmission was independently carried out by a board-certified geriatrician. Drug recommendations by ED physicians (A) and the geriatrician (B) were compared. RESULTS: There was a significantly higher frequency of recommendations regarding changes to preexisting medication (p <0.001, n = 50) via geriatric telemedicine in comparison with standard ED treatment. The geriatrician intervened significantly more often than the ED physicians: discontinuation of a drug, p <0.001; start of a new drug, p = 0.004; dose change of a drug, p = 0.001; n = 50). Based on the additional therapy recommendations of the geriatrician, the amount of medication taken by the patient was significantly reduced compared with standard ED treatment (ED assessment t(49) = 0.622 vs geriatrician’s assessment t(49) = 4.165; p <0.001; n = 50). Additionally, the number of PIMs was significantly reduced compared with standard medical treatment (p <0.001). The geriatrician changed 53.9% of the drugs (35/65) whereas the ED physicians changed only 12.3% (8/65). Recommendations for immediate drug therapy, however, were made more frequently by ED physicians (p <0.039, n = 50). DISCUSSION: An early assessment of elderly emergency patients by a geriatrician had a significant impact on the number of drug interventions in the ED. The number of PIMs could be significantly reduced. Whether this also has a positive effect on the further inpatient course needs to be investigated in further prospective studies. The study was retrospectively registered at ClinicalTrials.gov (NCT04148027).  .

Poor reporting quality of observational clinical studies comparing treatments of COVID-19 - a retrospective cross-sectional study.

BACKGROUND: During the COVID-19 pandemic, the scientific world is in urgent need for new evidence on the treatment of COVID patients. The reporting quality is crucial for transparent scientific publication. Concerns of data integrity, methodology and transparency were raised. Here, we assessed the adherence of observational studies comparing treatments of COVID 19 to the STROBE checklist in 2020. METHODS: Design: We performed a retrospective, cross-sectional study. SETTING: We conducted a systematic literature search in the Medline database. This study was performed at the RWTH Aachen University Hospital, Department of Anaesthesiology Participants: We extracted all observational studies on the treatment of COVID-19 patients from the year 2020. MAIN OUTCOME MEASURES: The adherence of each publication to the STROBE checklist items was analysed. The journals' impact factor (IF), the country of origin, the kind of investigated treatment and the month of publication were assessed. RESULTS: We analysed 147 observational studies and found a mean adherence of 45.6% to the STROBE checklist items. The percentage adherence per publication correlated significantly with the journals' IF (point estimate for the difference between 1st and 4th quartile 11.07%, 95% CI 5.12 to 17.02, p < 0.001). U.S. American authors gained significantly higher adherence to the checklist than Chinese authors, mean difference 9.10% (SD 2.85%, p = 0.023). CONCLUSIONS: We conclude a poor reporting quality of observational studies on the treatment of COVID-19 throughout the year 2020. A considerable improvement is mandatory.

Observational study of changes in utilization and outcomes in mechanical ventilation in COVID-19.

BACKGROUND: The role of non-invasive ventilation (NIV) in severe COVID-19 remains a matter of debate. Therefore, the utilization and outcome of NIV in COVID-19 in an unbiased cohort was determined. AIM: The aim was to provide a detailed account of hospitalized COVID-19 patients requiring non-invasive ventilation during their hospital stay. Furthermore, differences of patients treated with NIV between the first and second wave are explored. METHODS: Confirmed COVID-19 cases of claims data of the Local Health Care Funds with non-invasive and/or invasive mechanical ventilation (MV) in the spring and autumn pandemic period in 2020 were comparable analysed. RESULTS: Nationwide cohort of 17.023 cases (median/IQR age 71/61-80 years, 64% male) 7235 (42.5%) patients primarily received IMV without NIV, 4469 (26.3%) patients received NIV without subsequent intubation, and 3472 (20.4%) patients had NIV failure (NIV-F), defined by subsequent endotracheal intubation. The proportion of patients who received invasive MV decreased from 75% to 37% during the second period. Accordingly, the proportion of patients with NIV exclusively increased from 9% to 30%, and those failing NIV increased from 9% to 23%. Median length of hospital stay decreased from 26 to 21 days, and duration of MV decreased from 11.9 to 7.3 days. The NIV failure rate decreased from 49% to 43%. Overall mortality increased from 51% versus 54%. Mortality was 44% with NIV-only, 54% with IMV and 66% with NIV-F with mortality rates steadily increasing from 62% in early NIV-F (day 1) to 72% in late NIV-F (>4 days). CONCLUSIONS: Utilization of NIV rapidly increased during the autumn period, which was associated with a reduced duration of MV, but not with overall mortality. High NIV-F rates are associated with increased mortality, particularly in late NIV-F.

Teleconsultation for preoperative evaluation during the coronavirus disease 2019 pandemic: A technical and medical feasibility study.

BACKGROUND: During the surge in coronavirus disease 2019 (COVID-19) infections in early 2020, many medical organisations began developing strategies for implementing teleconsultation to maintain medical services during lockdown and to limit physical contact. Therefore, we developed a teleconsultation preoperative evaluation platform to replace on-site preoperative meetings. OBJECTIVE: This study assessed the feasibility of a teleconsultation for preoperative evaluation and procedure-associated adverse events. DESIGN: Implementation study. SETTING: A tertiary care university hospital in Germany from April 2020 to October 2020. PATIENTS: One hundred and eleven patients scheduled for elective surgery. INTERVENTION: Patients were assigned to receive teleconsultation for preoperative evaluation and to complete a subsequent survey. MAIN OUTCOME MEASURES: Primary endpoints were medical and technical feasibility, user satisfaction and time savings. RESULTS: For 100 out of 111 patients, telepreoperative consultations allowed for adequate perioperative risk assessment, patient education and also for effective collection of legal signatures. For six patients (5.4%), consultations could not be started because of technical issues, whereas for five patients (4.8%), clearance for surgery could not be granted because of medical reasons. A clear majority of anaesthetists (93.7%) rated the telepreoperative evaluations as equivalent to on-site meetings. The majority of the patients considered teleconsultation for preoperative evaluation as convenient as an on-site meeting (98.2%) and would choose a teleconsultation again (97.9%). Median travel time saved by patients was 60 min (Q1 40, Q3 80). We registered one adverse event: we detected atrial fibrillation in one patient only immediately prior to surgery. CONCLUSION: Telepreoperative evaluations are medically and technically feasible, yielding high satisfaction rates on both sides. However, regarding patient safety, not every patient is equally well suited. Overall, implementation of teleconsultation for preoperative evaluation into clinical routine could help maintain medical care during the COVID-19 pandemic. TRIAL REGISTRATION: NCT04518514, ClinicalTrials.gov.

Outcomes of Extracorporeal Membrane Oxygenation for Acute Respiratory Distress Syndrome in COVID-19 Patients: A Propensity-Matched Analysis.

It remains unclear to what extent the outcomes and complications of extracorporeal membrane oxygenation (ECMO) therapy in COVID-19 patients with acute respiratory distress syndrome (ARDS) differ from non-COVID-19 ARDS patients. In an observational, propensity-matched study, outcomes after ECMO support were compared between 19 COVID-19 patients suffering from ARDS (COVID group) and 34 matched non-COVID-19 ARDS patients (NCOVID group) from our historical cohort. A 1:2 propensity matching was performed based on respiratory ECMO survival prediction (RESP) score, age, gender, bilirubin, and creatinine levels. Patients' characteristics, laboratory parameters, adverse events, and 90-day survival were analyzed. Patients' characteristics in COVID and NCOVID groups were similar. Before ECMO initiation, fibrinogen levels were significantly higher in the COVID group (median: 493 vs. 364 mg/dL, p < 0.001). Median ECMO support duration was similar (16 vs. 13 days, p = 0.714, respectively). During ECMO therapy, patients in the COVID group developed significantly more thromboembolic events (TEE) than did those in the NCOVID group (42% vs. 12%, p = 0.031), which were mainly pulmonary artery embolism (PAE) (26% vs. 0%, p = 0.008). The rate of major bleeding events (42% vs. 62%, p = 0.263) was similar. Fibrinogen decreased significantly more in the COVID group than in the NCOVID group (p < 0.001), whereas D-dimer increased in the COVID group (p = 0.011). Additionally, 90-day mortality did not differ (47% vs. 74%; p = 0.064) between COVID and NCOVID groups. Compared with that in non-COVID-19 ARDS patients, ECMO support in COVID-19 patients was associated with comparable in-hospital mortality and similar bleeding rates but a higher incidence of TEE, especially PAE. In contrast, coagulation parameters differed between COVID and NCOVID patients.

Reducing Loneliness in Stationary Geriatric Care with Robots and Virtual Encounters-A Contribution to the COVID-19 Pandemic.

The bans on visiting nursing homes during the COVID-19 pandemic, while intended to protect residents, also have the risk of increasing the loneliness and social isolation that already existed among the older generations before the pandemic. To combat loneliness and social isolation in nursing homes, this trial presents a study during which social networks of nursing home residents and elderly hospital patients were maintained through virtual encounters and robots, respectively. The observational trial included volunteers who were either residents of nursing homes or patients in a geriatric hospital. Each volunteer was asked to fill in a questionnaire containing three questions to measure loneliness. The questionnaire also documented whether video telephony via the robot, an alternative contact option (for example, a phone call), or no contact with relatives had taken place. The aim was to work out the general acceptance and the benefits of virtual encounters using robots for different roles (users, relatives, nursing staff, facilities). Seventy volunteers with three possible interventions (non-contact, virtual encounters by means of a robot, and any other contact) took part in this trial. The frequency of use of the robot increased steadily over the course of the study, and it was regularly used in all facilities during the weeks of visitor bans (n = 134 times). In the hospital, loneliness decreased significantly among patients for whom the robot was used to provide contact (F(1,25) = 7.783, p = 0.01). In the nursing homes, no demonstrable effect could be achieved in this way, although the subject feedback from the users was consistently positive.

Influence of the COVID-19 Pandemic on the Prehospital Emergency and Tele-Emergency Care - a Comparative Cohort Study

Background The SARS-CoV-2 coronavirus, discovered in the city of Wuhan in November 2019, is now the cause of a pandemic with far-reaching consequences. Nevertheless, a decrease in the total number of emergency missions is reported. Method As part of a cohort analysis, the number of missions of EMS-physicians und tele-EMS-physicians from March 2020 was compared with March 2018 and 2019 with regard to potentially life-threatening diagnoses. In addition, all operational documentation of the ambulance, emergency medical service (EMS-)physician und tele-EMS-physician from the city of Aachen from March 2020 was evaluated. Results In March 2020, there was a significant decrease in emergency missions compared to 2018 and 2019 (p < 0.001). Potentially life-threatening missions decreased as well, however the proportion of them increased significantly from 52.3% (n = 294) in 2018 to 63.3% (n = 253) (p < 0.001). 39.6% (n = 89) of the 225 patients with infectious symptoms and normal vital signs were transported to the hospital by the ambulance without the involvement of a physician. Conclusion Above all, the number of non-life-threatening operations has declined. Despite normal vital signs, many patients were transported to the hospital by an ambulance. An increased consultation of the tele-EMS-physician could avoid transports that are not indicated.

Invasive and Non-Invasive Ventilation in Patients With COVID-19.

BACKGROUND: The reported high mortality of COVID-19 patients in intensive care has given rise to a debate over whether patients with this disease are being intubated too soon and might instead benefit from more non-invasive ventilation. METHODS: This review is based on articles published up to 12 June 2020 that were retrieved by a selective literature search on the topic of invasive and non-invasive ventilation for respiratory failure in COVID-19. Guideline recommendations and study data on patients with respiratory failure in settings other than COVID-19 are also considered, as are the current figures of the intensive care registry of the German Interdisciplinary Association for Intensive Care and Emergency Medicine (Deutsche Interdisziplinäre Vereinigung für Intensiv- und Notfallmedizin). RESULTS: The high mortality figures among patients receiving invasive ventilation that have been reported in studies from abroad cannot be uncritically applied to the current situation in Germany. Study data on ventilation specifically in COVID-19 patients would be needed to do justice to the special pathophysiology of this disease, but such data are lacking. Being intubated too early is evidently associated with risks for the patient, but being intubated too late is as well. A particularly im - portant consideration is the potential harm associated with prolonged spontaneous breathing, with or without non-invasive assistance, as any increase in respiratory work can seriously worsen respiratory failure. On the other hand, it is clearly unacceptable to intubate patients too early merely out of concern that the medical staff might become infected with COVID-19 if they were ventilated non-invasively. CONCLUSION: Nasal high flow, non-invasive ventilation, and invasive ventilation with intubation should be carried out in a stepwise treatment strategy, under appropriate intensive-care monitoring and with the observance of all relevant anti-infectious precautions. Germany is better prepared that other countries to provide COVID-19 patients with appropriate respiratory care, in view of the high per capita density of intensive-care beds and the availability of a nationwide, interdisciplinary intensive care registry for the guidance and coordination of intensive care in patients who need it.

Employment of Telemedicine in Nursing Homes: Clinical Requirement Analysis, System Development and First Test Results.

PURPOSE: Demographic change and lack of specialized workforces are challenging. Likewise, home visits by general practitioners (GPs) become rarer. If a nursing home resident develops acute symptoms, nurses are often inclined to call the rescue service. Besides patient-related consequences, this might lead to unnecessary hospitalization and far-reaching health economic costs. Due to legal restrictions of remote treatment in Germany, which were recently loosened, telemedicine is still in the early stages. The aim of this study was to employ a holistic telemedical system for nursing homes which facilitates the connection to a GP and thus avoids unnecessary hospitalizations in the case of ambulatory-sensitive illnesses. MATERIALS AND METHODS: After an inter-professional requirement analysis, the iterative development was started. In addition to an audio-video connection, several point of care measurements were integrated. Finally, first field tests were performed in a nursing home in a rural area in Germany. RESULTS: One nursing home was equipped with telemedical system based on the results of the requirement analysis and tele-medically connected to a GP. Over a period of seven months, 56 routine and emergency teleconsultations took place. Only one of those required a hospital admission. In addition to video telephony, electrocardiography and assessment of vitals such as pulse, blood pressure, oxygen saturation and auscultation of heart and lungs were applied frequently. CONCLUSION: A telemedical system including integrated medical devices was successfully developed and has turned out to be helpful and even necessary for careful and reliable decision-making by the GP. First test results show high acceptance for elderly care. Involved patients, nurses, and the GP itemize various specific benefits, including economic, personal, and altruistic issues. Another issue that the current COVID-19 crisis brought to light is lowering the risk of contagion; GPs can replace their home visits by using telepresence combined with point of care measures.
